Find LCM of 816,646,238,435,832 with Prime Factorization
| 2 | 816, 646, 238, 435, 832 |
| 2 | 408, 323, 119, 435, 416 |
| 2 | 204, 323, 119, 435, 208 |
| 2 | 102, 323, 119, 435, 104 |
| 3 | 51, 323, 119, 435, 52 |
| 17 | 17, 323, 119, 145, 52 |
| 1, 19, 7, 145, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 1 x 19 x 7 x 145 x 52 = 818301120
Therefore, the lowest common multiple of 816,646,238,435,832 is 818301120.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
816 x 646 x 238 x 435 x 832 = 45405892546560
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
646 : 1, 2, 17, 19, 34, 38, 323, 646
238 : 1, 2, 7, 14, 17, 34, 119, 238
435 : 1, 3, 5, 15, 29, 87, 145, 435
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,646,238,435,832, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
646:2x 17x 19
238:2x 7x 17
435:3x 5x 29
832:2x 2x 2x 2x 2x 2x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 3x 17x 17 = 55488
Therefore, the value for common factors is 55488.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 45405892546560/(1x55488)
LCM = 45405892546560/55488
LCM = 818301120
Thus, we can understand that the LCM of 816,646,238,435,832 is 818301120.
